Description

一种信息传输方法、装置及系统 技术领域
本申请涉及无线通信技术领域，尤其涉及一种信息传输方法、装置及系统。
背景技术
卫星通信是指利用人造地球卫星作为中继站来转发无线电波，实现两个或多个网络设备之间通信的技术。与传统的陆基通信相比，卫星通信具有覆盖范围广、传输距离远、组网灵活、部署方便等特点。卫星通信网络与第五代移动通信系统新空口技术(5th generation mobile networks new radio，5G NR)、长期演进技术(long term evolution，LTE)等陆基通信融合，能够极大扩展无线通信网络的覆盖范围。
由于卫星距离地面的距离较远，用户设备(user equipment，UE)在卫星小区内各个位置相对于卫星的距离变化不大，因此UE在小区边缘和小区中心接收到的信号强度差别不大，这就导致了当UE位于小区边缘时，受到相邻小区的信号干扰强度较大。为了克服干扰，卫星采用极化复用方式进行信号传输，即不同的卫星小区采用不同的极化方式进行信号传输。在这种方式下，当UE从一个小区切换至另一个目标小区，或者当UE进行目标小区的选择或重选时，由于UE预先不知道目标小区采用的是哪一种极化方式，因此UE需要开启各种极化方式对应的端口对目标小区进行测量，导致UE在进行小区切换、小区选择或者小区重选时的能耗较高。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚地描述。在本申请的描述中，除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；本申请中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，在本申请的描述中，“多个”是指两个或两个以上。
在对本申请实施例的技术方案说明之前，首先对本申请实施例的技术场景进行说明。
本申请实施例提供的技术方案可以应用于卫星通信系统中。其中，卫星通信是指利用人造地球卫星作为中继站来转发无线电波，实现两个或多个网络设备之间通信的技术。与传统的陆基通信相比，卫星通信具有覆盖范围广、传输距离远、组网灵活、部署方便和不受地理条件限制等特点，可以广泛应用到海上通信、定位导航、抢险救灾、科学实验、视频广播和对地观测等诸多领域。卫星通信系统可以与第五代移动通信系统新空口技术(5th generation mobile networks new radio，5G NR)、长期演进技术(long term evolution，LTE)、全球移动通信系统(global system for mobile communication，GSM)和通用移动通信系统(universal mobile telecommunications system，UMTS)等陆基无线通信系统融合，实现数据传输的互联互通，因此能够极大地扩展陆基无线通信网络的覆盖范围，与陆基无线通信系统取长补短，共同构成全球无缝覆盖的海、陆、空、天一体化的综合网络通信系统。
图1是目前的卫星通信系统的架构图。如图1所示，卫星通信网络可以包括一个或者多个卫星基站、一个或者多个用户设备(user equipment，UE)，以及一个或者多个核心网(core network)设备组成。
示例性地，本申请实施例的卫星基站指的是可以作为各类无线通信系统基站(例如：演进型基站(eNB)和5G基站(gNB)等)的人造地球卫星和高空飞行器等，卫星基站通过NG接口以无线连接的方式连接到核心网设备，并向用户设备提供无线通信服务。NG接口是指卫星基站和核心网之间接口，主要交互核心网的NAS等信令，以及用户的业务数据。容易理解的是，在卫星通信系统中，每个卫星基站可以覆盖一个有限的地理区域，并可以为该地理区域内的用户设备提供无线通信服务；这样的地理区域可以被划分成一个或者多个具有唯一标识的位置区(location area)，这样的位置区可被称作小区(cell)，位置区的唯一标识即作为小区的小区ID；为了便于描述本申请实施例的技术方案，本申请实施例在后续的描述中将卫星基站的小区称为卫星小区。
示例性地，一个卫星基站可以包括一个或者多个卫星小区。例如，如图1所示，卫星基站1包括小区1、小区2和小区3，卫星基站2包括小区4，卫星基站3包括小区5和小区6。其中，当卫星基站包括多个卫星小区时，卫星小区可以是根据卫星基站的波束确定的，例如：每个波束的覆盖范围作为一个小区，卫星小区也可以是根据一些规则划分的，例如将卫星基站的覆盖范围划分成相邻的几个小区等。
示例性地，本申请实施例的卫星基站从轨道类型的角度划分，可以包括静止轨道(geostationary earth orbit，GEO)卫星、非静止轨道(none-geostationary earth orbit，NGEO)的中轨道(medium earth orbit，MEO)卫星和低轨道(low earth orbit，LEO)卫星，以及高 空通信平台(high altitude platform station，HAPS)等；从通信能力角度划分，卫星基站可以包括常规通信卫星和高通量卫星(high throughput satellite，HTS)等。本申请实施例对该卫星基站的具体形态不作特殊限制。
示例性地，本申请实施例的核心网设备可以包括接入和移动性管理功能网元(access and mobility management function，AMF)或者移动性管理网元(mobility management，MME)等。
示例性地，本申请实施例的用户设备可以是手机、平板电脑、桌面型、膝上型、手持计算机、笔记本电脑、超级移动个人计算机(ultra-mobile personal computer，UMPC)、上网本，以及蜂窝电话、个人数字助理(personal digital assistant，PDA)、无线调制解调器、增强现实(augmented reality，AR)\虚拟现实(virtual reality，VR)设备等包括触摸屏的设备、车载通信设备、机载通信设备、可穿戴设备等。本申请实施例对该用户设备的具体形态不作特殊限制。
图2是本申请实施例提供的用户设备100的结构示意图。如图2所示，用户设备100可以包括处理器110，存储器120，天线130和移动通信模块140。其中，处理器110可以包括一个或多个处理单元，例如：处理器110可以包括应用处理器(application processor，AP)，调制解调处理器，图形处理器(graphics processing unit，GPU)，图像信号处理器(image signal processor，ISP)，控制器，视频编解码器，数字信号处理器(digital signal processor，DSP)，基带处理器，和/或神经网络处理器(neural-network processing unit，NPU)等。其中，不同的处理单元可以是独立的器件，也可以集成在一个或多个处理器中。控制器可以根据指令操作码和时序信号，产生操作控制信号，完成取指令和执行指令的控制。
处理器110中还可以设置存储器，用于存储指令和数据。在一些实施例中，处理器110中的存储器为高速缓冲存储器。该存储器可以保存处理器110刚用过或循环使用的指令或数据。如果处理器110需要再次使用该指令或数据，可从存储器中直接调用。避免了重复存取，减少了处理器110的等待时间，因而提高了系统的效率。
用户设备100的无线通信功能可以通过天线130，移动通信模块140，调制解调处理器以及基带处理器等实现。其中，天线130包括至少一个天线面板，每个天线面板均可用于发射和接收电磁波信号，天线130可用于覆盖单个或多个通信频带。在另外一些实施例中，天线103可以和调谐开关结合使用。
移动通信模块140可以提供应用在用户设备100上的包括2G/3G/4G/5G等无线通信的解决方案。移动通信模块140可以包括至少一个滤波器，开关，功率放大器，低噪声放大器(low noise amplifier，LNA)等。移动通信模块140可以由天线130接收电磁波，并对接收的电磁波进行滤波，放大等处理，传送至调制解调处理器进行解调。移动通信模块140还可以对经调制解调处理器调制后的信号放大，经天线130转为电磁波辐射出去。在一些实施例中，移动通信模块140的至少部分功能模块可以被设置于处理器110中。在一些实施例中，移动通信模块140的至少部分功能模块可以与处理器110的至少部分模块被设置在同一个器件中。
调制解调处理器可以包括调制器和解调器。其中，调制器用于将待发送的低频基带信号调制成中高频信号。解调器用于将接收的电磁波信号解调为低频基带信号。随后解调器将解调得到的低频基带信号传送至基带处理器处理。低频基带信号经基带处理器处理后，被传递给应用处理器。应用处理器通过音频设备输出声音信号，或通过显示屏显示图像或视频。在一些实施例中，调制解调处理器可以是独立的器件。在另一些实施例中，调制解调处理器可以独立于处理器110，与移动通信模块140或其他功能模块设置在同一个器件中。
在一些实施例中，用户设备100的天线130和移动通信模块140耦合，使得用户设备100 可以通过无线通信技术与网络以及其他设备通信。无线通信技术可以包括第五代移动通信技术新空口(5th generation mobile networks new radio，5G NR)，全球移动通讯系统(global system for mobile communications，GSM)，通用分组无线服务(general packet radio service，GPRS)，码分多址接入(code division multiple access，CDMA)，宽带码分多址(wideband code division multiple access，WCDMA)，时分码分多址(time-division code division multiple access，TD-SCDMA)，长期演进技术(long term evolution，LTE)等。
存储器120可以用于存储计算机可执行程序代码，可执行程序代码包括指令。存储器120可以包括存储程序区和存储数据区。其中，存储程序区可存储操作系统，至少一个功能所需的应用程序(比如声音播放功能，图像播放功能等)等。存储数据区可存储用户设备100使用过程中所创建的数据(比如音频数据，电话本等)等。此外，存储器120可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件，闪存器件，通用闪存存储器(universal flash storage，UFS)等。处理器110通过运行存储在存储器120的指令，和/或存储在设置于处理器中的存储器的指令，执行用户设备100的各种功能应用以及数据处理。
可以理解的是，本申请实施例示意的结构并不构成对用户设备100的具体限定。在本申请另一些实施例中，用户设备100可以包括比图示更多或更少的部件，或者组合某些部件，或者拆分某些部件，或者不同的部件布置。图示的部件可以以硬件，软件或软件和硬件的组合实现。
图3是卫星通信系统中的用户设备相对于卫星小区的位置变化场景图。
如图3所示，在卫星通信系统中，一方面，由于用户设备可能产生位移，用户设备相对于卫星基站的位置会发生改变，导致用户设备相对卫星小区的位置会发生变化，例如：从卫星小区的中心位移到了卫星小区的边缘，或者，从一个卫星小区(例如：卫星小区1)位移到了另一个卫星小区(例如：卫星小区2)；另一方面，当卫星基站是非静止轨道卫星时，卫星基站会围绕地球旋转，因此卫星小区的位置也会随着卫星基站的旋转而不断变化，在这种情况下，即使用户设备的位置没有发生变化，用户设备相对卫星小区的位置也会发生变化，因此同样会导致上述用户设备从一个卫星小区(例如：卫星小区1)进入到另一个卫星小区(例如：卫星小区2)。
为了便于描述本申请实施例的技术方案，结合图3所示的场景，本申请实施例可对卫星小区进行以下命名区分：在“用户设备从一个卫星小区进入到另一个卫星小区”这一过程中，所述“一个卫星小区”为源小区或者服务小区，所述“另一个卫星小区”为目标小区。例如：如果用户设备从卫星小区1进入到卫星小区2，那么卫星小区1为源小区或者服务小区，卫星小区2为目标小区；如果用户设备从卫星小区2进入到卫星小区3，那么卫星小区2是源小区或者服务小区，卫星小区3为目标小区。进一步地，在本申请实施例中，服务小区归属的基站可以称作源基站或者服务基站，目标小区归属的基站可以称作目标基站。
进一步结合图3所示的场景，由于卫星基站可以包括一个或者多个小区，因此，当用户设备从服务小区进入到目标小区时，服务小区和目标小区可能属于同一个卫星基站，例如卫星小区1和卫星小区2同属于卫星基站1；服务小区和目标小区也可能属于不同的卫星基站，例如卫星小区2属于卫星基站1，而卫星小区3属于卫星基站2。因此，在“用户设备从一个卫星小区进入到另一个卫星小区”这一过程中，服务基站和目标基站可能是同一个卫星基站，也可能是不同的卫星基站。
图4是用户设备在卫星小区的不同位置与卫星基站的距离示意图。如图4所示，在卫星通信系统中，由于卫星基站相对于地面的高度较高，用户设备在卫星小区的不同位置与卫星 基站的距离差△h占据用户设备与卫星基站距离h的比例不大，导致卫星小区内的卫星信号的远近效应(即：由距离差导致的卫星信号强度的变化效应)不明显。因此，用户设备在卫星小区内的各个位置接收到的卫星信号的强度差别不大(根据已知的数据，用户设备在小区边缘和小区中心接收到的卫星信号的强度差在3dB左右)，在这种情况下，如果用户设备位于服务小区的边缘，就会收到相邻小区的高强度的信号干扰。
为了克服相邻小区的干扰，卫星通信系统使用对不同的卫星小区使用了频率复用和极化复用等技术。示例性地，图5是卫星通信的频率/极化方式四色复用的示意图，如图5所示，在四色复用的图谱中，每个六边形表示一个卫星小区，六边形的填充样式表示卫星小区的频率(freq)和/或极化方式，不同的填充样式对应的信号频率和/或极化方式不同。在图5所示的四色复用方案中，任意一个卫星小区与其所有相邻小区的信号频率和/或极化方式都是不同的。示例地，当四色复用采用频率四等分的方式实现时，需要配置四个不同频率f1、f2、f3和f4，此时，相邻的卫星小区的信号频率不同。又例如，当四色复用采用频率二等分加极化复用的方式实现时，可以使用两个不同的信号频率f1和f3(此时，图5中的f1＝f2，f3＝f4)，以及两种不同的极化方式，例如左旋圆极化(left hand circular polarization，LHCP)和左旋圆极化(right hand circular polarization，DHCP)，得到频率和极化方式的四种组合，并配置相邻的卫星小区采用不同的组合方式。
图6是电磁波极化方式的示意图。下面将结合图6对本申请实施例中涉及到的左旋圆极化和左旋圆极化做进一步阐述说明。极化(polarization)也称偏振，指的是横波(例如在空间中传播的电磁波)能够朝着不同方向振荡的性质。电磁波的电场与磁场彼此相互垂直。按照常规，电磁波的偏振方向指的是电场的偏振方向。在自由空间里，电磁波是以横波方式传播，即电场与磁场都垂直于电磁波的传播方向。如果电场的振荡只朝着单独一个方向，则称此为“线极化”或“平面极化”；如果电场的振荡方向是以电磁波的波频率进行旋转动作，并且电场矢量随着时间变化勾绘出圆型，则称此为“圆极化”，如果勾绘出椭圆形，则称此为“椭圆极化”；对于“圆极化”来说，从电磁波的源头向电磁波的传播方向望去，如果电场随时间的变化呈现逆时针方向旋转，则电磁波的极化方式为左旋圆极化，如果电场随时间的变化呈现顺时针方向旋转，则电磁波的极化方式为右旋圆极化；对于“椭圆极化”来说，从电磁波的源头向电磁波的传播方向望去，如果电场随时间的变化呈现逆时针方向旋转，则电磁波的极化方式为左旋椭圆极化，如果电场随时间的变化呈现顺时针方向旋转，则电磁波的极化方式为右旋椭圆极化。
图7是极化复用场景中用户设备接收卫星信号的示意图。如图7所示，为了保证用户设备能够正确接收并解调卫星基站以各种极化方式发送的卫星信号，用户设备需要为每一种极化方式配置相应的接收端口，从而能够根据服务基站的卫星信号的极化方式选择对应的接收端口进行卫星信号的接收和解调。也就是说，只有卫星信号的极化方式与接收端口的极化方式相同时，用户设备才能够正确接收并解调卫星信号。进一步如图7所示，在极化复用场景中，当用户设备从源小区进入到目标小区时，由于用户设备预先不知道目标小区采用的是哪一种极化方式，用户设备需要同时开启所有极化方式对应的端口，以此保证能够正确接收并解调目标小区的卫星信号。但是，同时开启所有极化方式对应的端口会增加用户设备的功耗，并且，还可能使用户设备接收并解调到其他相邻小区的卫星信号，从而对目标小区的信号接收和解调造成干扰。
本申请实施例提供的方法中，可以在用户设备从源小区进入到目标小区之前，使用户设备获取到目标小区的极化方式。这样，用户设备就可以在进行小区切换和重选时，根据目标 小区的极化方式，仅开启目标小区的极化方式对应的端口接收卫星信号，并对目标小区进行小测量，完成小区切换和重选流程。由此，本申请实施例提供的方法，可以降低用户设备在进行小区切换时的能耗，以及避免受到其他相邻小区的信号干扰。
本申请实施例提供的一种信息传输方法可以应用到无线通信系统中，所述无线通信系统包括但不限于：卫星通信系统、第五代移动通信系统新空口技5G NR、长期演进技术LTE、全球移动通信系统GSM、通用移动通信系统UMTS和无线局域网Wi-Fi等。基于上述各类无线通信系统，本申请实施例提供的一种无线网络中的小区极化方式的执行主体可以包括上述任意无线通信系统用户侧的用户设备(例如：用户设备100)，以及上述任意通信系统网络侧的网络设备(例如：卫星基站(包括演进型基站eNB、5G基站gNB等)，以及在地面建设的演进型基站eNB、5G基站gNB、无线AP(Access Point)和用户驻地设备(customer-premises equipment，CPE)等)。下面以卫星通信系统为例，对本申请实施例提供的一种信息传输方法进行具体地阐述说明。
实施例(一)
本申请实施例提供了一种信息传输方法。如图8所示，该方法可以包括步骤S201-S203。
步骤S201，服务基站在无线资源控制(radio resource control，RRC)消息中配置第一指示信息，所述第一指示信息为极化方式指示信息，极化方式指示信息用于指示目标小区的极化方式或者部分带宽BWP的极化方式。其中，所述部分带宽BWP的极化方式的具体消息格式在实施例六中具体描述。
具体实现中，极化方式指示信息例如可以配置在RRC消息的移动控制信息消息元素(MobilityControlInfo information element)字段中。作为示例地，包含有极化方式指示信息的移动控制信息消息元素可以具有以下的消息格式：
MobilityControlInfo information element
--ASN1开始(--ASN1START)
--标签-测量-配置-开始(--TAG-MEAS-CONFIG-START)
测量配置(MeasureConfig)：：＝序列(Sequence){极化方式(Polarization)示例(ENUMERATED){左旋圆极化(LHCP)，右旋圆极化(RHCP)}}
--标签-测量-配置-结束(--TAG-MEAS-CONFIG-STOP)
--ASN1结束(--ASN1STOP)
示例性地，上述移动控制信息消息元素中的极化方式(Polarization)字段的内容可以参照表1描述的方式实现：
Figure PCTCN2020114469-appb-000001
表1
根据表1的描述，目标小区的极化方式(Polarization)可以通过在RRC消息中增加一个长度为1bit(比特)的比特值来指示，对应目标小区可能使用例如左旋圆极化或右旋圆极化这两种极化方式的情况。此时，可以使用比特值1来指示左旋圆极化，使用比特值0来指示右旋圆极化，或者，也可以使用比特值1来指示右旋圆极化，使用比特值1来指示左旋圆极化。这里需要补充说明的是，比特值1和比特值0具体指示的目标小区的极化方式可以由服务基站和用户设备通过协商确定，也可以根据相应的配置和协议确定，本申请实施例中对比 特值和极化方式的对应关系不做具体限定。
示例性地，上述移动控制信息消息元素中的极化方式(Polarization)字段的内容可以参照表2描述的方式实现：
Figure PCTCN2020114469-appb-000002
表2
根据表2的描述，目标小区的极化方式(Polarization)可以通过在RRC消息中增加一个长度为2bit(比特)的比特值序列来指示，对应目标小区可能存两种或者多于两种极化方式的情况。例如，当目标小区可能使用左旋圆极化、右旋圆极化、左旋椭圆极化或者右旋椭圆极化时，可以使用比特值序列00来表示左旋圆极化，使用比特值序列01来表示右旋圆极化，使用比特值序列10来表示左旋椭圆极化，使用比特值序列11来表示右旋椭圆极化。这里需要补充说明的是，比特值序列的不同值具体指示的目标小区的极化方式可以由服务基站和用户设备通过协商确定，也可以根据相应的配置和协议确定，并配置在用户设备和服务基站中，本申请实施例中对比特值序列和极化方式的对应关系不做具体限定。
容易理解的是，本申请实施例在RRC消息中增加的用于指示目标小区的极化方式的比特值或比特值序列的长度是可以根据目标小区可能使用的极化方式的数量确定的。因此，上述比特值或比特值序列的长度可以不局限于1bit或者2bit。当目标小区可能使用更多的极化方式传输卫星信号时，本领域技术人员在本申请实施例公开的基础上容易想到继续增加上述比特值序列的长度，例如3bit、4bit等，以指示更多的极化方式，这些都没有超出本申请实施例的保护范围。
需要补充说明的是，在步骤S201的具体实现方式中，极化方式指示信息可以用于指示服务小区的多个相邻小区的极化方式，其中，用户设备切换的目标小区是多个相邻小区中的一个。极化方式指示信息如表3所示具体可以包括相邻小区的小区ID(Cell ID，CID)和对应用于指示极化方式的比特值或比特值序列。

表3
步骤S202，服务基站向用户设备发送包含极化方式指示信息的RRC消息。
以第五代移动通信系统新空口技术(5th generation mobile networks new radio，5G NR)和长期演进技术(long term evolution，LTE)为例，用户设备和服务基站之间可以包括两种或者三种RRC状态。具体来说：5G NR中用户设备和服务基站可以包括三种RRC状态，分别为：RRC连接态(RRC_CONNECTED)、RRC空闲态(RRC_IDLE)和RRC待用态(RRC_INACTIVE)；LTE中用户设备和服务基站可以包括两种RRC状态，分别为：RRC连接态(RRC_CONNECTED)和RRC空闲态(RRC_IDLE)。
其中，在RRC连接态中，用户设备和服务基站之间建立有RRC连接，用户设备可以与服务基站交互信令或者数据，并且当UE小区间移动时，网络侧会控制用户设备进行小区切 换(例如用户设备从服务小区切换到目标小区)，即网络侧控制用户设备的移动性。在RRC空闲态中，用户设备和基站之间没有RRC连接，如果用户设备需要和基站之间交互信令或者数据，需要向基站发起RRC连接，以从RRC空闲态进入到RRC连接态；用户设备在RRC空闲态会监听基站的寻呼信息；用户设备在小区间移动时，会进行小区重选，即用户设备控制自身的移动性。在RRC待用态中，用户设备和基站之间没有RRC连接，但是用户设备的最后一个服务基站保存有用户设备的上下文信息，以快速从RRC待用态转移到RRC连接态；用户设备在小区间移动时，会进行小区重选，即用户设备控制自身的移动性。
根据上述可能的RRC状态，步骤S202可以选择在RRC连接态中实现。当用户设备和服务基站处于RRC连接态时，服务基站和用户设备之间建立有RRC连接，服务基站可以通过RRC连接向用户设备发送包含极化方式指示信息的RRC消息。
需要补充说明的是，在步骤S202的具体实现方式中：服务基站可以主动向用户设备发送包含极化方式指示信息的RRC消息，而不需要收到用户设备的任何请求；或者，用户设备也可以主动向服务基站发起用于获取极化指示信息的请求消息，使服务基站在接收到该请求消息的情况下，根据该请求消息向用户设备发送包含极化方式指示信息的RRC消息。
可选的，当用户设备从服务基站的RRC消息中解调得到上述极化指示信息时，用户设备还可以向服务基站发送一个确认消息，例如ACK消息(message acknowledgment)，以指示服务基站不需要继续向用户设备发送包含极化指示信息的RRC消息，降低信令开销。
步骤S203，用户设备根据所述目标小区的极化方式或者BWP的极化方式与所述目标小区进行通信。
进一步地，所述用于设备根据所述目标小区的极化方式，开启对应的端口对目标小区进行测量。
图9是本申请实施提供的用户设备进行小区切换的场景示意图。如图9所示，在RRC连接态下，当用户设备从服务小区移动到目标小区时，用户设备可以执行小区切换流程。小区切换流程一般可以包括以下3个步骤：
步骤一：测量；用户设备对目标小区进行小区测量，并向服务基站上报测量结果。
步骤二：判决；服务基站评估测量结果，并考虑用户设备的区域限制情况，判定是否进行小区切换。
步骤三：切换；当服务基站确定进行小区切换时，对用户设备进行RRC连接重新配置，使用户设备对目标小区执行随机接入流程，并与目标小区建立RRC连接。
本申请实施例的步骤S203，至少能够降低用户设备在小区切换流程中的小区测量步骤(即步骤一)的能耗，并且提高小区测量结果的准确性。具体实现中，服务基站可以通知用户设备需要测量的对象(例如：信号与干扰加噪声比(signal to interference plus noise ratio，SINR)、参考信号接收质量(reference signal receiving quality，RSRQ)、参考信号接收功率(reference signal receiving power，RSRP)等)、小区列表、测量结果报告方式、测量标识等参数；用户设备根据上述参数确定要测量的目标小区，并根据极化方式指示信息所指示的目标小区的极化方式，开启对应的端口对目标小区进行测量，并将测量结果上报给服务基站。
示例地，如图9所示，用户设备在移动到目标小区之前，从服务基站接收到极化方式指示信息；如果该极化方式指示信息指示目标小区的极化方式为右旋圆极化，那么，当用户设备移动到目标小区时，用户设备可以仅开启右旋圆极化对应的端口对目标小区进行测量，而无需开启所有的端口，由此，能够降低用户设备在小区测量时的能耗；并且，由于用户设备不开启其他极化方式对应的端口，用户设备不会解调到通过其他极化方式传输的电磁波信号， 避免了用户设备在进行目标小区测量时受到干扰，提高测量结果的准确性。
需要补充说明的是，本申请实施例中的极化方式对应的端口，可以是物理端口，也可以是逻辑端口。其中，物理端口例如可以是用户设备的天线端口；逻辑端口例如可以是通过参考信号区分的(reference signal)或链路区分的逻辑端口，具体来说，当多个物理天线用于传输一个参考信号时，这些物理天线就可以对应同一个逻辑端口，当不同链路的参考信号通过同一个物理天线传输时，这个物理天线就可以对应多个逻辑端口。本申请实施例对极化方式对应的端口的具体形式不做限定。
由以上描述可知，本申请实施例提供的方法，服务基站在RRC消息中配置极化方式指示信息，使用户设备在进行小区切换之前，提前获知目标小区的极化方式，从而在进行小区切换时，可以根据目标小区的极化方式开启对应的端口对目标小区进行小区测量，而不需要开启多个端口。由此，本申请实施例提供的方法能够降低用户设备在小区切换时的能耗，并且避免用户设备在进行小区测量时受到来自其他小区的干扰，提高测量结果的准确性。
实施例(二)
本申请实施例提供了一种信息传输方法。如图10所示，该方法可以包括步骤S301-S303。
步骤S301，服务基站在服务小区的系统广播消息(system information block，SIB)中配置极化方式指示信息，极化方式指示信息用于指示目标小区的极化方式或者用于指示BWP的极化方式。
具体实现中，系统广播消息SIB通常包含多个类型，例如SIB1～SIBx(其中，x为大于1的正整数)，极化方式指示信息可以配置在系统广播消息SIB的某一个或者多个类型中。
作为示例地，在5G NR和LTE系统中，一些SIB类型包含小区重选相关的信息，例如：
●SIB2包含小区重选信息，主要与服务小区有关；
●SIB3包含关于与小区重选相关的服务频率和频内相邻小区的信息；
●SIB4包含关于与小区重选相关的其他NR频率和频率间相邻小区的信息；
因此，服务基站可以优选将极化方式指示信息配置在SIB2、SIB3或者SIB4等包含小区重选相关信息的SIB类型中。
作为示例地，包含有极化方式指示信息的系统广播消息SIBx可以具有以下的消息格式：
SIBx message
--ASN1开始(--ASN1START)
--标签-测量-配置-开始(--TAG-MEAS-CONFIG-START)
系统广播消息(SIBx)：：＝序列(Sequence){极化方式(Polarization)示例(ENUMERATED){左旋圆极化(LHCP)，右旋圆极化(RHCP)}}
--标签-测量-配置-结束(--TAG-MEAS-CONFIG-STOP)
--ASN1结束(--ASN1STOP)
示例性地，上述系统广播消息SIBx中的极化方式(Polarization)字段的内容可以参照表4描述的方式实现：
Figure PCTCN2020114469-appb-000003
表4
根据表4的描述，目标小区的极化方式(Polarization)可以通过在系统广播消息SIBx中 增加一个长度为1bit(比特)的比特值来指示。例如，当目标小区可能使用左旋圆极化或右旋圆极化这两种极化方式时，可以使用比特值1来指示左旋圆极化，使用比特值0来指示右旋圆极化，或者，可以使用比特值1来指示右旋圆极化，使用比特值1来指示左旋圆极化。这里需要补充说明的是，比特值1和比特值0具体指示的目标小区的极化方式可以由服务基站和用户设备通过协商确定，也可以根据相应的配置和协议确定，本申请实施例中对比特值和极化方式的对应关系不做具体限定。
示例性地，上述系统广播消息SIBx中的极化方式(Polarization)字段的内容可以参照表5描述的方式实现：
Figure PCTCN2020114469-appb-000004
表5
根据表2的描述，目标小区的极化方式(Polarization)可以通过在系统广播消息SIBx中增加一个长度为2bit(比特)的比特值序列来指示，以指示目标小区可能存在的更多的极化方式。使用2bit长度的比特值序列指示极化方式的具体示例，请参照本申请的实施例(一)，此处不再赘述。
容易理解的是，本申请实施例在系统广播消息SIBx中增加的用于指示目标小区的极化方式的比特值或比特值序列的长度是可以根据目标小区可能使用的极化方式的数量确定的。因此，上述比特值或比特值序列的长度可以不局限于1bit或者2bit。当目标小区可能使用更多的极化方式传输卫星信号时，本领域技术人员在本申请实施例公开的基础上容易想到继续增加上述比特值序列的长度，例如3bit、4bit等，以指示更多的极化方式，这些都没有超出本申请实施例的保护范围。
需要补充说明的是，在步骤S301的具体实现方式中，极化方式指示信息可以用于指示服务小区，以及服务小区的多个相邻小区的极化方式；其中，用户设备进行小区选择或者小区重选的目标小区可以是服务小区，也可以是多个相邻小区中的一个。极化方式指示信息用于指示多个小区的极化方式的具体示例，可以参照实施例(一)的表3实现，此处不再赘述。
步骤S302，服务基站向用户设备发送包含极化方式指示信息的系统广播消息。
根据实施例(一)描述的内容，用户设备可以包括三种RRC状态，分别为：RRC连接态、RRC空闲态和RRC待用态。步骤S302可以选择在RRC空闲态或RRC待用态中实现。例如，当用户设备和服务基站处于RRC空闲态时，服务基站和用户设备之间没有RRC连接，服务基站可以通过系统广播消息SIBx向用户设备发送极化方式指示信息。
具体实现中，服务基站可以周期性地在特定SI(SystemInformation)窗口发送系统广播消息SIBx，因此，用户设备可以周期性地在对应地SI窗口接收并解码系统广播消息SIBx，由此获得极化方式指示信息。
步骤S303，用户设备根据第一指示信息与所述目标小区进行通信。
进一步地，用户设备可以根据极化方式指示信息所指示的目标小区的极化方式，开启对应的端口对目标小区进行测量。
一般来说，用户设备在开机后会执行小区选择流程，以便尽快选择一个信道质量满足条件的小区进行驻留；在用户设备执行小区选择流程之后，在RRC空闲态(RRC_IDLE)状态下，用户设备需要持续地进行小区重选，以便驻留在优先级更高或者信道质量更好的小区。
类似于小区切换流程，用户设备在执行小区选择或者小区重选流程时，同样需要对目标 小区进行小区测量。本申请实施例的步骤S304，能够降低用户设备在小区选择或者小区重选流程中的小区测量的能耗，并且提高小区测量结果的准确性。
图11是本申请实施提供的用户设备进行小区重选的场景示意图。示例地，如图11所示，在RRC空闲态下，用户设备接收其驻留的服务小区的包含极化方式指示信息的系统广播消息，如果该极化方式指示信息指示目标小区的极化方式为右旋圆极化，那么，当用户设备位于目标小区时，如果要进行小区选择或重选，用户设备可以仅开启右旋圆极化对应的端口对目标小区进行测量，而无需开启所有的端口，由此，能够降低用户设备在小区测量时的能耗；并且，由于用户设备不开启其他极化方式对应的端口，用户设备不会解调到通过其他极化方式传输的电磁波信号，避免了用户设备在进行目标小区测量时受到干扰，提高测量结果的准确性。
需要补充说明的是，在用户设备执行小区重选或者选择流程前后，用户设备前后驻留的小区可能是同一个小区，即服务小区和目标小区是同一个小区；用户设备前后驻留的小区也可能不是同一个小区，即服务小区和目标小区是不同的小区。由此可见，结合实施例(一)和实施例(二)，本申请实施例中的服务小区和目标小区，是根据用户设备在小区切换、重选、选择流程前后接入的小区定义的，不构成对小区在地理层面的划分或者隔离。
由以上描述可知，本申请实施例提供的方法，服务基站在服务小区的系统广播消息中配置极化方式指示信息，使用户设备获知目标小区的极化方式，从而在进行小区选择和重选时，可以根据目标小区的极化方式开启对应的端口对目标小区进行小区测量，而不需要开启多个端口。由此，本申请实施例提供的方法能够降低用户设备在小区选择和重选时的能耗，并且避免用户设备在进行小区测量时受到来自其他小区的干扰，提高测量结果的准确性。
实施例(三)
本申请实施例提供了一种无线网络中的极化方式指示方法。如图12所示，该方法可以包括步骤S401-S403。
步骤S401，卫星基站在下行控制消息(downlink control information，DCI)中配置极化方式指示信息，极化方式指示信息用于指示用户设备接收当前小区信号的极化方式或者BWP的极化方式。
具体实现中，当前小区是指用户设备当前接入的卫星小区，包括上述服务小区和目标小区，卫星基站是指当前小区归属的基站，包括上述服务基站和目标基站。一个卫星小区可以同时存在多种极化方式的小区信号，当卫星小区接入了多个用户设备时，卫星基站可以针对每个用户设备使用不同的极化方式发送小区信号，并将每个用户设备接收小区信号时应该采用的极化方式配置在该用户设备对应的下行控制消息中。
图13是下行寻呼信息的消息格式示意图。如图13所示，一般来说，下行控制消息可以是长度为N bit的比特值序列，N为大于或者等于1的正整数。根据实施例(一)和实施例(二)对极化方式指示信息的描述，根据小区可能使用的极化方式的数量，极化方式指示信息可以是长度为1bit的比特值、或者长度为2bit、3bit以及其他长度的比特值序列。那么，结合下行控制消息的消息格式，可以将下行控制消息的某一个或者多个比特值作为极化方式指示信息。
示例地，当卫星小区包括左旋圆极化或右旋圆极化这两种极化方式时，极化方式指示信息是长度为1bit的比特值，例如，可以使用比特值1来指示左旋圆极化，使用比特值0来指示右旋圆极化。该1bit的比特值如图12所示可以是下行控制消息的第一个比特值，也可以是其他位置的比特值。由此，当下行控制消息的第一个比特值为1时，指示用户设备使用左 旋圆极化接收小区信号，当下行控制消息的第一个比特值为0时，指示用户设备使用右旋圆极化接收小区信号。
步骤S402，卫星基站向用户设备发送包含极化方式指示信息的下行控制消息。
具体实现中，卫星基站在物理下行控制信道(physical downlink control channel，PDCCH)传输下行控制消息DCI，因此，用户设备可以在物理下行控制信道PDCCH接收下行控制消息DCI，以获取极化方式指示信息。
卫星基站可以在PDCCH周期性地发送下行控制消息DCI，用户设备可以周期性地在下行控制消息DCI发送窗口监听PDCCH，以接收到下行控制消息DCI。卫星基站和用户设备发送和接收下行控制消息DCI的具体方式可以根据现有的技术规范或标准实施，本申请实施例中不做具体限定。
步骤S403，用户设备根据极化方式指示信息，与所述目标小区进行通信。例如，用于设备根据指示的目标小区的极化方式，开启对应的端口接收小区信号。
示例地，如果极化方式指示信息指示用户设备应该使用左旋圆极化接收小区信号，则用户设备可以仅开启左旋圆极化对应的端口接收小区信号，而不需要开启其他的端口。其中，用户设备接收小区信号例如可以是在下行控制消息DCI指示的物理下行共享信道(physical downlink shared channel，PDSCH)所在位置进行小区信号的接收和解调等。
由以上描述可知，本申请实施例提供的方法，卫星基站在下行控制消息DCI中配置极化方式指示信息，使用户设备获知用于接收小区信号的极化方式，并开启极化方式对应的端口接收小区信号，而不需要开启多个端口。由此，本申请实施例提供的方法能够降低用户设备与基站通信时的能耗，还能避免用户设备受到来自其他小区的干扰。
实施例(四)
本申请实施例提供了一种信息传输方法。该方法能够实现在相邻的两个或者多个基站之间共享各自小区的极化方式，使基站能够根据相邻小区的极化方式合理确定自身小区的极化方式，由此提升小区之间的干扰协调能力。
图14是基站之间共享小区极化方式的场景图。如图14所示，基站之间可以通过Xn接口应用流程协议(XnAP)消息传输小区的极化方式。Xn接口是指卫星基站和卫星基站之间的接口，主要用于切换等信令交互。下面以XnAP消息的发送方作为源基站，以XnAP消息的接收方作为邻基站，以源基站的小区作为源小区，以邻基站的小区作为邻小区，对基站之间传输小区的极化方式的过程进行阐述说明：
具体实现中，源基站可以在XnAP消息中定义新的极化状态消息(Polarization Status)，其中，该极化状态消息包含源小区的极化方式。当源基站上电使能或者源小区的极化方式变化时，源基站将极化状态消息发送给邻基站，使邻基站获取源小区最新的极化方式，或者，当邻基站已经记录有源小区的极化方式时，邻基站可以根据最新获取的极状态的信息更新源小区的极化方式。
作为示例地，极化状态消息可以具有如以下表6的消息格式：
Figure PCTCN2020114469-appb-000005
Figure PCTCN2020114469-appb-000006
表6
由以上描述可知，本申请实施例提供的方法，源基站在发给邻小区的XnAP消息中增加极化状态消息，以向邻小区指示源小区的极化方式，使邻基站能够根据源小区的极化方式合理确定自身邻小区的极化方式，由此提升小区之间的干扰协调能力。
实施例(五)
本申请实施例提供了一种信息传输方法。该方法将小区信号不同的极化方式与不同的指示信息建立关联，那么，如果用户设备确定了其接收到的小区信号的极化方式，则意味着用户设备接收到了该极化方式所关联的指示信息，由此，用户设备无需额外发送这一指示信息，有利于提高用户设备与基站之间信息传输的吞吐率。
具体实现中，极化方式可以关联一个长度为1bit的信息，不同的极化方式对应不同的信息值。例如，左旋圆极化可以对应比特值0，右旋圆极化可以对应比特值1，此时，当用户设备接收到左旋圆极化的小区信号时，说明用户设备接收到了比特值0，当用户设备接收到右旋圆极化的小区信号时，说明用户设备接收到了比特值1。又例如，左旋圆极化可以对应比特值1，右旋圆极化可以对应比特值0，此时，当用户设备接收到左旋圆极化的小区信号时，说明用户设备接收到了比特值1，当用户设备接收到右旋圆极化的小区信号时，说明用户设备接收到了比特值0。
具体实现中，极化方式可以用于指示广播消息，例如：主系统广播消息(master information block，MIB)、系统广播消息(system information block，SIB)等；极化方式关联的信息还可以作为基站向用户设备传输的数据消息。
示例地，极化方式可以用于指示主系统广播消息MIB中的cell barred参数，该cell barred参数指示小区是否被禁止接入。例如：当cell barred参数值为1时，表示小区被禁止接入，当cell barred参数值为0时，表示小区未被禁止接入。图15是卫星基站通过极化方式指示cell barred参数的示意图。如图15所示，用户设备可以小区切换、小区选择或者小区重选时，开启全部极化方式对应的端口用户设备接收小区信号。如果用户设备在左旋圆极化对应的端口接收到小区信号，则小区信号为左旋圆极化，对应cell barred参数值为0，表示小区未被禁止接入；如果用户设备在右旋圆极化对应的端口接收到小区信号，则小区信号为右旋圆极化，对应cell barred参数值为1，表示小区被禁止接入。
进一步地，用户设备在确定了小区信号的极化方式和极化方式所指示的广播消息或者数据消息之后，可以关闭其他极化方式对应的端口，以降低功耗。
本申请实施例中，不同极化方式与不同指示信息的对应关系，以及对不同信息值的定义可以由基站和用户设备协商确定，也可以根据相应的配置和协议确定，本申请实施例对此不做具体限定。
由以上描述可知，本申请实施例提供的方法，利用小区信号的极化方式指示其他信息，例如广播消息或者数据消息，由此，用户设备无需额外发送这一信息，有利于提高用户设备与基站之间信息传输的吞吐率。

所述网络设备以服务基站为例，所述第一指示信息可以承载在所述在服务小区的无线资源控制(radio resource control，RRC)消息中或者系统广播消息(system information block，SIB)，这里以所述RRC中配置BWP的极化方式指示信息为例进行说明，上述实施例中以RRC或者SIB消息中配置BWP的极化方式指示信息均可以使用。
具体实现中，极化方式指示信息例如可以配置在RRC消息的BWP信息消息元素(BWP Info information element)字段中。
也可以为：系统广播消息SIB通常包含多个类型，例如SIB1～SIBx(其中，x为大于1的正整数)，极化方式指示信息可以配置在系统广播消息SIB的某一个或者多个类型中。
用户设备所在BWP的极化方式具体可以包括：用户设备所在的目标小区公共BWP的极化方式以及用户设备特有的BWP的极化方式。
作为示例地，包含有极化方式指示信息的移动控制信息消息元素可以具有以下的消息格式：
具体BWP information element消息格式如下：
Figure PCTCN2020114469-appb-000007
示例性地，上述部分带宽消息元素中的极化方式(Polarization)字段的内容可以参照下面表7实现：
Figure PCTCN2020114469-appb-000008
表7
根据表7的描述，目标小区的极化方式(Polarization)可以通过在RRC消息中增加一个长度为1bit(比特)的比特值来指示，对应目标小区可能使用例如左旋圆极化或右旋圆极化这两种极化方式的情况。此时，可以使用比特值1来指示左旋圆极化，使用比特值0来指示右旋圆极化，或者，也可以使用比特值1来指示右旋圆极化，使用比特值1来指示左旋圆极化。这里需要补充说明的是，比特值1和比特值0具体指示的目标小区的极化方式可以由服务基站和用户设备通过协商确定，也可以根据相应的配置和协议确定，本申请实施例中对比特值和极化方式的对应关系不做具体限定。
示例性地，上述移动控制信息消息元素中的极化方式(Polarization)字段的内容可以参照表8描述的方式实现：
Figure PCTCN2020114469-appb-000009
表8
根据上面表8的描述，目标小区的极化方式(Polarization)可以通过在RRC消息中增加一个长度为2bit(比特)的比特值序列来指示，对应目标小区可能存两种或者多于两种极化方式的情况。例如，当目标小区可能使用左旋圆极化、右旋圆极化、左旋椭圆极化或者右旋椭圆极化时，可以使用比特值序列00来表示左旋圆极化，使用比特值序列01来表示右旋圆极化，使用比特值序列10来表示左旋椭圆极化，使用比特值序列11来表示右旋椭圆极化。这里需要补充说明的是，比特值序列的不同值具体指示的目标小区的极化方式可以由服务基站和用户设备通过协商确定，也可以根据相应的配置和协议确定，并配置在用户设备和服务 基站中，本申请实施例中对比特值序列和极化方式的对应关系不做具体限定。
容易理解的是，本申请实施例在RRC消息中增加的用于指示目标小区的极化方式的比特值或比特值序列的长度是可以根据目标小区可能使用的极化方式的数量确定的。因此，上述比特值或比特值序列的长度可以不局限于1bit或者2bit。当目标小区可能使用更多的极化方式传输卫星信号时，本领域技术人员在本申请实施例公开的基础上容易想到继续增加上述比特值序列的长度，例如3bit、4bit等，以指示更多的极化方式，这些都没有超出本申请实施例的保护范围。
需要补充说明的是，在步骤S501的具体实现方式中，极化方式指示信息可以用于指示目标小区的多个BWP的极化方式，其中，用户设备的目标小区的BWP是多个BWP中的一个。极化方式指示信息如表9所示，具体可以包括目标小区ID(Cell ID，CID)、部分带宽ID(BWP ID)和对应用于BWP的指示极化方式的比特值或比特值序列。
根据表9的描述，在CID为4600012345的目标小区中，包含BWP ID为00、01、10和11等多个BWP，其中，BWP 00对应的极化方式为左旋圆极化，用比特值0来指示，BWP 01对应的极化方式为右旋圆极化，用比特值1来指示。
小区ID BWP ID 极化方式
4600012345 00 0
4600012345 01 1
4600012345 10 1
4600012345 11 0
…… …… ……
表9
步骤S502，网络设备向用户设备发送包含极化方式指示信息的RRC消息。
以第五代移动通信系统新空口技术(5th generation mobile networks new radio，5G NR)和长期演进技术(long term evolution，LTE)为例，用户设备和服务基站之间可以包括两种或者三种RRC状态。具体来说：5G NR中用户设备和服务基站可以包括三种RRC状态，分别为：RRC连接态(RRC_CONNECTED)、RRC空闲态(RRC_IDLE)和RRC待用态(RRC_INACTIVE)；LTE中用户设备和服务基站可以包括两种RRC状态，分别为：RRC连接态(RRC_CONNECTED)和RRC空闲态(RRC_IDLE)。
其中，在RRC连接态中，用户设备和服务基站之间建立有RRC连接，用户设备可以与服务基站交互信令或者数据，并且当UE小区间移动时，网络侧会控制用户设备进行小区切换(例如用户设备从服务小区切换到目标小区)，即网络侧控制用户设备的移动性。在RRC空闲态中，用户设备和基站之间没有RRC连接，如果用户设备需要和基站之间交互信令或者数据，需要向基站发起RRC连接，以从RRC空闲态进入到RRC连接态；用户设备在RRC空闲态会监听基站的寻呼信息；用户设备在小区间移动时，会进行小区重选，即用户设备控制自身的移动性。在RRC待用态中，用户设备和基站之间没有RRC连接，但是用户设备的最后一个服务基站保存有用户设备的上下文信息，以快速从RRC待用态转移到RRC连接态；用户设备在小区间移动时，会进行小区重选，即用户设备控制自身的移动性。
根据上述可能的RRC状态，步骤S502可以选择在RRC连接态中实现。当用户设备和服务基站处于RRC连接态时，服务基站和用户设备之间建立有RRC连接，服务基站可以通过RRC连接向用户设备发送包含极化方式指示信息的RRC消息。
需要补充说明的是，在步骤S502的具体实现方式中：服务基站可以主动向用户设备发送包含极化方式指示信息的RRC消息，而不需要收到用户设备的任何请求；或者，用户设备也可以主动向服务基站发起用于获取极化指示信息的请求消息，使服务基站在接收到该请求消息的情况下，根据该请求消息向用户设备发送包含极化方式指示信息的RRC消息。
可选的，当用户设备从服务基站的RRC消息中解调得到上述极化指示信息时，用户设备还可以向服务基站发送一个确认消息，例如ACK消息(message acknowledgment)，以指示服务基站不需要继续向用户设备发送包含极化指示信息的RRC消息，降低信令开销。
步骤S503，用户设备根据所述第一指示信息与所述目标小区进行通信。
上述实施例中提供的方法中，用户设备获取第一指示信息，所述第一指示信息包括部分带宽BWP的极化方式，所述用户设备根据所述第一指示信息发送或者接收所述目标小区的小区信号。由此，上述提供的一种在BWP中增加极化指示的方法，可以支持不同波束或用户设备在给定部分带宽BWP中以指示用户设备通过指示的极化方式完成通信传输，同时降低了受到其他相邻小区的信号干扰。
另外，上述实施例中装置部分的描述均是用于实施例六的描述，这里就不再赘述。
